Answer:

Step-by-step explanation:

olve: x - 6 = -12 Solve: x + 6 = -12 Solve: x/6 = -12 Solve: 6x = -12 ... Solve: 3 + 2x = 4x - 1 Solve: 3x + 4(x -1) = 2 Solve: 4x + 2 - 3x + 5 - 2(x + 5) = (2x - 5) + (3x + 4) ... Notice in equation 10, that until you get to the equation "-x - 3 = 5x - 1, " all ... 3 = 2x - 1 +1 = + 1 4 = 2x 4/2 = 2x/2 2 = x, the answer, 9.) Solve: 3 + 2x = 4x - 1

Wich of the following is a factor of both (2y)3 + (y)2 and (4y)4 + (2y)3

dem82 [27]

Answer:

y^2

Step-by-step explanation:

2y^3 + y^2 and 4y^4 + 2y^3

2y^3 + y^2......factor out y^2

y^2(2y + 1)

4y^4 + 2y^3...factor out y^2

y^2(4y^2 + 2y)

I would normally factor out 2y^3 out of this one...but u cant do it in the other one...the only common factor is gonna be y^2

the common factor is y^2 <===

A basketball player made 12 out of 15 free throws she attempted. She wants to know how many consecutive free throws she would ha

klemol [59]

Answer:

a) $\frac{12+n}{15+n}=0.85$

b) She needs 5 consecutive free throws in order to raise her percent to

85 %

Step-by-step explanation:

We know that a basketball player made 12 out of 15 free throws she attempted.

We can calculate its percent of successful free throws as :

$\frac{12}{15}=0.8$

$(0.8).(100)=80$ %

Now, If she wants to know how many consecutive free throws she would have to make to raise the percent of successful free throws to 85 % we can write :

$\frac{12+n}{15+n}=0.85$ (I)

In the equation (I) ''n'' represents the number of consecutive free throws she must have to raise the percent to 85 %.

We answer

a) $\frac{12+n}{15+n}=0.85$

b) Now we need to solve the equation (I) :

$\frac{12+n}{15+n}=0.85$ ⇒

$12+n=(15+n).(0.85)$ ⇒
